So that's one reason? Dunno if they are being honest or not, but I guess maybe the arms get fatigued from repeated articulation. Given that they also sell their bushings without the arm, it doesn't seem like they are just trying to rip the customer off by offering them pre-installed in new arms.
This Dealer could be jumping the gun and suggesting they replace them on the first bushing change to make more money.

Could be because they're aluminum and pressing bushings in and out widens the hole out of tolerance (or maybe weakens it). On my ZO6, GM recommended not changing the ball joints at all but replacing the entire arm.
